This is sort of a curious concoction.  If you are actually adding K2O, 
you are adding an extremely strong base to a solution with ammonium 
sulfate in it.  The ammonium ions should be essentially quantitatively 
converted into ammonia, and the ammonia may be lost.  Did you notice any 
sort of ammoniacal odor from the mixture when you mixed it up?
